Five members of the violent Latino gang MS-13 were busted by the feds on charges of killing two Long Island residents they suspected of being police informants, authorities said yesterday.

A sixth suspect in the murders of Olivia Mendoza, 16, and Genaro “El Vago” Venegas, 24, is still being sought.

On Sept. 21, Venegas’ body was found in Bethpage, and Mendoza’s body was found in Old Westbury.

Authorities said an accused killer was secretly recorded admitting to MS-13 members that he rubbed out Mendoza with approval from gang leaders José “Estraño” Hernandez and José “Psycho” Recinos, both 25, who are among those facing possible life sentences.

At least two additional gangsters were taped boasting about their roles in the Venegas slaying, the feds said.

The suspect still sought in the Mendoza and Venegas killings was identified as Jovanic “Sonic” Berrios, 20.
